Liam Hemsworth was among attendees at the VIP pre-fight party for "Showtime PPV's presentation of The One: Floyd Mayweather, Jr. vs. Canelo Alvarez" on September 14. According to E! News, Liam attended the event with Jeff Beacher and other guy friends. "Twilight" actress Ashley Greene was also with them.

Wearing white t-shirt with light blue button-up, Liam was in "good spirits," bobbing his head to Ne-Yo's song which was played at the event and took pictures with fans, according to a source. "He seemed really chill and in good spirits. He was just hanging out with his friends. It was a guys' weekend in Vegas," the source said.

The Gale Hawthorne of "The Hunger Games" reportedly only stayed for 30 minutes at the bash. Besides Liam, other celebrities such as Dave Chappelle, Busta Rhymes, Heidi Klum, Jerry Bruckheimer, LL Cool J and Justin Bieber were also present.

Fans found out earlier that day that Liam's fiancee Miley Cyrus stopped following him on Twitter, although the actor was still following the "Wrecking Ball" singer on the social media. The couple previously was under media's scrutiny after Liam was romantically linked to "Mad Men" actress January Jones. However, a representative for the 23-year-old star has slammed the allegation, calling it "tabloid fiction."
